INTUITIVE VISUAL TABS- Intuitive visual and numbered tabs easily let you find content for future reference.
- Open as many tabs as you like without losing track of your open Web pages.
EASY ACCESS TO YOUR TOP SITES- Spend your time reading your favorites sites instead of looking for them.
ADD-ONS FOR EVERYTHING- Take control of your Web experience by personalizing Firefox with add-ons like ad blockers, password and download managers and more.
